2G/3G Cellular Traffic over PSN
• Aggregation and tunneling (pseudo-wire) of both 2G TDM traffic and 3G ATM traffic over the same packet transport network
• Mapping of TDM/ATM traffic to packets • Clock distribution and network synchronization

HSDPA Application – Cellular Backhaul over PSN/ATM
• Cell Site Gateway performs separation of traffic (if required)
• UMTS HSDPA data traffic mapped to pseudo-wires over PSN (standard ATMoPSN support)
• Ensures QoS for voice and real-time traffic

Summary
The PW solution enables:
• Smooth migration to new packet based transport networks
• Good for voice, data and video traffic
• Provide a complete solution for TDM, ATM and DSL services over PSN using RAD PW products
• Transparent to protocols and signaling
• Reducing the cost by avoiding the need to use leased lines
• Controlled transport costs by maximizing utilization of RAN infrastructure
• Standardized by the IETF PWE3 working group
